. .Beit known Vthat I, EUGENE CHAHN, of St. Louis,-

in th'ecounty of St; Louis, and State of Missouri, have invented a new `and useful Improved Drinking# Tube for Invalidsgf and I do-hereby g declare that the following is a'full and true` description thereof', refer- 4en c'e beinghad to theaccompanying drawings and to the letters of reference marked'thereon.

i The `invalid is compelled to change from a reclin-4 ing to asitting posturefand then, in drinking, the Huidsfrequently spill, and wetor soil the bedding or clolbingof the patient, causing discomfort and even in# jury." Usually, in drinking from larger vessels, the aid ofthe attendantornurse is necessary, which, while itincreases the conditions Yof Vdependence of. the patient lupon others, is otherwise ohjectioiiable'for reasons ofv "economy -g To 1 avoid said, disadvantagesiand to 'place within `clout-rol of the patient (ifisuclrbedesirable) the sup` u plyof his drink or liuid medicine, I have Varranged 'a i tube with suitablemouth-piece andproperinfluent-pipe and attachment bracket, so that the said tube may i i readily be connected to thelvessel containingthe fluid,

and whilst said 'vessel will be placed conve'nientlyVin. proximityto the patient, yet the samernay 'not be in.

suchiposition as to canseinconvenience or damage to the patient if theuidbe spilt or wasted.

To enable those herein skilled to make and use my ,said invention, I will now more fully describethe same, referring-herein to the accompanying- FigureLas a general elevation of the 'tube as attached toa vessel containing water orother fluid, theY vessel being shown-in section; and to Figure 2 as a bottom pla-n. y

I use a tube `A, usually of rubber, but the same may beof any other material of suitable flexibility. Said thisbeing so formed .as to be readily retained in the mouth.

sibly also of other material. The pipe C has a closed lbottom c and a side inlet opening c', at some distance sediment is prevented, served open.

has a vertical shank E; the latter forms thenut for or other washer end, f.

The tube is connected with the vessel containing the fluid, by placing the influent pipe C into the vessel vertically, so thatfthe side of the vesselsball come then, by setting 'the 'screw up tight against the ontside of the vessel, a firm support-is obtained. By thus clamping thevessel sidebetween the pipe O andthe screw F, a very simple connectionhasxbeen achieved; which is secure in its adjustment, and may nevertheless be readily disjointed. 4 4

The patient draws the nidthrough Athe tube A in the manner readily understood.

`Having,r thus fully described my invention,
